Patent CA-2285718-A1 (CA)
Inventor: SHERBANIUK GLENN
IPC: G01F15/08
Filed: 1999-09-27
Abstract: The design and operating characteristics of this invention is radically different from conventional oil/gas separators. It incorporates a vertical stripping section joined to a horizontal separating section by a 180 degree loop at the bottom of the vertical section. At the end of the horizontal section there is a 90 degree drop which swedges down to the pipe size of the liquid metering section.   At the top of the vertical and horizontal section the piping connects to the gas cap side of the separation system. The gas piping runs from the discharge side of the horizontal section to the inlet side of the horizontal where it joins in with the gas piping off of the vertical section. From there it runs through the gas metering section. At the bottom of the 180 degree loop there is a blow-down point for produced sand and debris.

Title: Interleaving methodology and apparatus for cdma
Inventor: CHHEDA ASHVIN
IPC: H04L1/02
Filed: 1999-10-08
Abstract: Disclosed is an encoder, interleaves and splitter design approach for increasing system capacity. This is accomplished in a dual path embodiment by splitting the data stream into two subsets where one subset contains even number position bits of the original set and the other subset comprises the remaining odd bits.      Each of the subsets may then be interleaved in standard fashion. This approach ensures that consecutively occurring bits in the original set are never transmitted from the same antenna and can be used to maximize the distance (and accordingly the time of transmission) between alternately occurring bits . The thought process behind this embodiment of the invention may be used to design a single interleaves as practiced in the prior art to accomplish the equivalent end result. The design process may be modified to include any number of transmission paths.      Additional improvement of capacity may be obtained where each subset is interleaved in a manner to maximize the time separation between transmission of data bits, originally occurring L bits apart, prior to splitting or interleaving, in each of L data paths.
